Abstract

To simplify a multi-level surface laser level structure.
A weight 120 on which laser modules 130, 190, a prism 140, a spectroscopic mirror 180, and cylindrical lenses 150, 160, 170 are arranged is pin-joined on a shelf as a support casing, and the weight is less than the shelf. The vertical direction is set to enable rotational movement around the axial direction.
A laser beam 131 generated by the laser module 130 is split by a roof prism, and a split beam 132 is transmitted horizontally to develop a horizontal laser beam surface from a cylindrical lens 150, and the split beam 133 is further split by a spectroscope 180. Thus, the split light beam 134 is transmitted in an oblique direction, and the split light beam 135 is transmitted vertically upward, and developed in the respective directions by the cylindrical lenses 160 and 170, respectively. Below the vertical axis, the laser beam 191 passes through the weight from the laser module 190 and serves as an index.

Description

  The present invention relates to a laser level, and more particularly to a multi-surface laser level with a simple structure.

With the development of science and technology, the laser level has already been widely applied to construction and renovation work, and has become an auxiliary tool for adjusting the horizontal or vertical level during construction. The laser level of the automatic reference adjustment generates a laser beam surface that is the reference of the horizontal or vertical level by automatic reference adjustment, and the construction can be performed accurately by projecting the reference horizontal or vertical line on the target. In recent years, the building and renovation industry has been in the spotlight.

In the prior art, there are many types of multi-surface laser levels with automatic weight adjustment, but due to the restrictions that require the laser light source used by each laser surface, the price and volume of the laser level can be simplified. It's getting harder. For example, there are patents such as Republic of China No. 270172 “Stereoscopic Projecting Leveling Projector”, Republic of China No. 570188 “Improvement of Multi-Directional Laser Level” and Republic of China No. M247820 “Laserable Laser Instrument”. The disclosed laser level generates each laser beam surface by using a laser light source individually, and due to this complicated configuration, it is not easy to reduce the price and volume of the multi-beam surface laser level.

  An object of the present invention is to provide a multi-light surface laser level with a simple structure capable of generating a plurality of laser light surfaces using a laser module and further reducing the price and volume of the laser level.

In order to achieve the above object, the “multi-beam surface laser level” provided by the present invention is: shelf, weight, laser module, first spectroscopic mirror, first columnar mirror (lens), and second spectroscopic It includes a mirror and a second columnar mirror (lens). Among them, the weight is pin-joined on the shelf, and can rotate in at least two axial directions corresponding to the shelf so that the center of gravity of the weight can define a vertical line along the direction of gravity. The laser module is installed in a weight and is used to generate a laser beam that is transmitted along a vertical direction. The first spectroscopic mirror is installed on the transmission path of the laser beam in the weight, and splits the laser beam to generate a first split light beam and a second split light beam. The first columnar lens is installed on the transmission path of the first split light beam in the weight, and converts the first split light beam into a laser beam surface. The second spectroscopic mirror is installed on the transmission path of the second split light beam in the weight, and splits the second split light beam again to generate a third split light beam and a fourth split light beam. The second columnar lens is installed on the transmission path of the third split light beam in the weight, and converts the third split light beam into another laser light surface.

  The present invention provides a multi-beam surface laser level having a simple structure capable of generating a plurality of laser beam surfaces using a laser module and further reducing the price and volume of the laser level.

1 to 4 show examples of the multi-light surface laser level. In the figure, the laser level 100 is: a shelf 110, a weight 120 that is pin-joined on the shelf 110, rotationally moved about at least two axes with respect to the shelf, and a green light emitting laser module 130 installed in the weight 120. The roof-type prism 140, the cylindrical lenses 150, 160 and 170, the spectroscopic mirror 180 and the red light emitting laser module 190 are included. As will be appreciated by those skilled in the art, the cylindrical lenses 150, 160, and 170 can be replaced by selectively using different columnar lenses such as semi-cylindrical lenses.

Of these, the weight 120 includes a weight body 121, a prism table 124, and a spectroscopic table 125. The prism base 124 is screwed into the screw hole 301 of the weight main body 121 by the screw 201 and fixed on the weight main body 121, and is used for mounting the roof prism 140 and the cylindrical lens 150.
The spectroscopic table 125 is respectively screwed into the screw holes 302 of the prism table 124 by screws 202 and fixed on the prism table 124, and is used for mounting the spectroscope 180 and the cylindrical lenses 160 and 170.

Further, the through hole 303 of the weight main body 121 has a shaft 123 pierced, and both ends are respectively pin-joined to the through holes 304 and 305 of the bearing base 122 by bearings (not shown) so that the weight 120 follows the direction of gravity. The rotational movement around the first axial direction 401 is made possible. The through holes 306 and 307 of the bearing base 122 are pin-joined on the shelf 110 by other bearings (not shown) so that the weight 120 can rotate around the second axial direction 402 according to the direction of gravity.
As described above, the weight 120 is swung by the influence of gravity, and the center of gravity of the weight 120 is defined so that the vertical line 501 can be defined in the direction of gravity. The vertical line 501 is accurately positioned on the central axis of the weight 120. To do. As shown in FIG. 3, the green light emitting laser module 130 is disposed on the central axis of the weight 120 in the vertical direction, and allows the generated laser beam 131 to be transmitted along the vertical line 501. On the other hand, it is possible to avoid an increase in the volume of the weight 120 that occurs when it is disposed laterally and to simplify the structure.

  The roof prism 140 is installed on the transmission path of the laser beam 131 in the weight 120, and is used to split the laser beam 131 and generate split beams 132 and 133 orthogonal to each other. The split beam 132 is transmitted in the horizontal direction and is incident on a cylindrical lens 150 placed vertically. The cylindrical lens 150 develops the split beam 132 on a horizontal laser beam surface orthogonal to the vertical line 121, and this horizontal laser. The light surface can project a horizontal reference line on the vertical surface to provide a construction horizontal level reference line.

  The split beam 133 is transmitted along the direction of the vertical line 501 and is incident on the spectroscopic mirror 180 to further split the split beam 133 to generate split beams 134 and 135. The split beam 134 is transmitted almost in the horizontal direction but slightly upward and is incident on the cylindrical lens 160 of the horizontal device. The cylindrical lens 160 develops the split beam 134 on a vertical laser beam surface parallel to the vertical line 121. The vertical laser beam surface can project a vertical reference line onto the vertical plane to be a construction vertical level reference line.

  Among them, the transmission direction of the split beam 134 is a reference line that allows the split beam 134 to be transmitted close to the horizontal but slightly upward by projecting on the vertical plane by finely adjusting the angle of the spectroscope 180. In addition, the emission angles of the divided light beams 134 and 135 generated by the spectroscopic mirror 180 are 90 degrees or less.

  Further, the split beam 135 is transmitted along the direction of the vertical line 501 and is incident on the cylindrical lens 170. The cylindrical lens 170 is developed on the laser beam surface that projects the split beam 135 upward, and extends to the vertical plane on the ceiling plate. It is used to project a reference line orthogonal to the reference line to be used, and an intersection reference point extending upward from the vertical line 501 to the ceiling board is indicated.

In FIG. 3, the red light emitting laser module 190 is arranged on the center line of the weight in the vertical direction, and the generated laser beam 191 is transmitted downward along the vertical line 501, projected onto the ground plane, and projected onto the vertical line 501. In addition, a reference point perpendicular to the ground plane is indicated, and a corresponding reference from the bottom to the top is provided to the builder in correspondence with the reference point of the ceiling board.
